Embodiment Construction

[0056] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0057] In order to solve the problem of RF probe calibration, first introduce the composition and measurement principle of RF probes. It consists of three vibrators, foam body, connecting rod, and connecting aviation plug. The three vibrators form the three axes of X, Y, and Z, and are integrated into the foam body. This is the core part of the sensor.

[0058] The principle of measuring the radio frequency electric field is: the radio frequency electric field...

Abstract

The invention provides a radio frequency probe calibration method and calibration device, and the device comprises a radio frequency electric field measuring instrument, a rotating tray rack, a clamping rotating mechanism, a transverse wave chamber, a radio frequency probe, a high-frequency signal generator, a power amplifier, a high-frequency millivoltmeter, an attenuator, and a computer. The radio frequency electric field measuring instrument is installed on the rotating tray rack. the radio frequency electric field measuring instrument is connected to the radio frequency probe through the probe conduit; the probe conduit is mounted on the clamping and rotating mechanism, and the radio frequency probe is located in the transverse wave chamber; the output end of the high-frequency signal generator is connected with the input end of the power amplifier, and the output end of the power amplifier is connected to one end of the transverse wave chamber; the high-frequency millivoltmeter is connected to the attenuator, and the attenuator is connected to the other end of the transverse wave chamber; and the radio frequency electric field measuring instrument is connected to the computer. The device is attractive in structural appearance and accurate and convenient to operate, the labor intensity is reduced, and the working efficiency and the qualified rate of products are improved.

Description

technical field [0001] The invention relates to the field of radio frequency probe calibration, in particular to a radio frequency probe calibration method and a calibration device. Background technique [0002] With the development of economic construction and the advancement of science and technology, my country has made gratifying achievements in power equipment, communication networks, and transportation. The development of various fields and the application of advanced electronic equipment make people's life fast and convenient, not only improving people's material and cultural living standards, but also bringing us a new topic: how to measure and protect electromagnetic radiation. [0003] A large number of electronic devices emit electromagnetic energy while operating normally, which may have adverse effects on other devices, or even cause serious harm. This is electromagnetic interference. Under the conditions of limited time, space and limited frequency resources, ...
